Mystery Boards
« on: June 24, 2021, 12:48:25 am »
Does anyone know what kind of device these boards are from?

The logo of the top board is unknown while logo on the second board is for Burroughs.

The boards appear to be from the late 1960's.

Any help would be greatly appreciated!   :D

I like how it's a modern pcb but the designer has laid it out exactly like a turret board anyway -could '59 be design year?

Burroughs mainly made early computers, adding machines and the like. Lack of diodes or actives means it's not logic boards. I think the other logo is an older Burroughs logo.

It appears to be a voltmeter multiplier.  The resistors are 1% and there is a trimmer to improve bandwidth. And those numbers are the date.
